Reflection: Developing a Conceptual Understanding Temperature, Heat, Exothermic, and Endothermic Reactions - Section 10: Evaluate


The goal of this lesson is for students to really understand how energy flows when a substance is heated up. 

Through the various activities where I showed students HOW to model as well as gave them a chance to visualize how energy flows I felt that students met the objective. 

However, for the homework some students still had a hard time doing a model of what happens when a piece of hot metal was placed in cold water.  Therefore, I realize that students need to do more practice with this concepts. 

This is something that I will continue to stress throughout the unit a students work with the concepts of temperature, energy, heat, and modeling.

Temperature, Heat, Exothermic, and Endothermic Reactions

Unit 5: Unit 6: Energy
Lesson 2 of 9

Objective: Students will be able to differentiate between temperature and heat as well as exothermic and endothermic reactions through taking notes, performing lab activities, and drawing models.

Big Idea: Temperature is a measure of the average kinetic energy of molecules and can change as heat flows between objects. This change in heat for chemical reactions can be considered endothermic or exothermic.
